Abstract: Physical and chemical characteristics of soil from strata of an ancient cultural site is important to paleoenvironment reconstruction. This study investigated cultural and natural soil profiles in the Yingpanshan site, an ancient cultural site in the upper reaches of the Minjiang river, by analyzing particle size distribution, magnetic susceptibility, element geochemistry, organic matter and carbonate contents of soil samples. Our result showed that ancient human activities did affect the characteristics of soil, such as particle size, magnetic susceptibility, organic matter, carbonate and element migration, causing inconsistent changes among environmental indices. A warmer and moister climatic feature was presented in the drought valley of upper Minjiang river during the mid-late Holocene, which could be demonstrated by pedogenic features of the paleosol above the ash layer. A better reconstruction of paleoenvironment using soils from cultural strata, demands great attentions on multi-proxies and avoiding information mislead by human activities.
